Question

我是PHP的初学者，我正在尝试网站注册等等。我一直在收到错误＆＃34;意外的＆＃39;赶上＆＃39; （T_CATCH）在第67和34行的C：\ wamp \ www \ ass \ signup.php中;每当我点击我的注册表单上提交时（它以不同的html格式）。以下是我在html表单上点击提交时调用的php文件的代码。如果这里有很多菜鸟错误，请帮助和非常抱歉。正如我所说，我是初学者。

    <?php

include('connect.php');

$username =$_POST['username'];
$firstname = $_Post['firstName'];
$lastname = $_Post['lastName'];
$emailadd = $_POST['emailAdd'];
$gender = $_POST['gender'];
$userpassword = $_Post['userPassword'];
$dayofbirth = $_POST['dayOfBirth'];
$monthofbirth = $_POST['monthOfBirth'];
$yearofbirth = $_POST['yearOfBirth'];
$profiledesc = $_POST['profileDesc'];

$date = $_POST['yearOfBirth'] . '-' . $_POST['monthOfBirth'] . '-' . $_POST['dayOfBirth'];


    try {
    $host = "localhost";
    $username = "root";
    $password = "";
    $database = "users";
    $dsn = "mysql:host=$host;dbname=$database";

    $conn = new PDO( $dsn, $username, $password );
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "INSERT INTO userProfile("
    . "username, firstName, lastName, emailAdd, gender, userPassword, birthday, profileDesc" 
    . " ) VALUES (" 
    . "'" . $lastname . "',"
    . "'" . $firstname . "',"
    . "'" . $emailadd . "',"
    . "'" . $gender ."';"
    . "'" . $userpassword ."';"
    . "'" . $date ."';"
    . "'" . $profiledesc ."';";


    $conn->query($sql);

    $sql = "SELECT * FROM users";
    $users = $conn-query($sql);
    echo '<table>';
    echo '<tr>';
    echo '<th>First Name</th>
          <th>Last Name</th>
          <th>Email Address</th>
          <th>Gender</th>';
    echo '<tr>';
    foreach ($users as $users) {
    echo '<tr>';
    echo '  <td>' . $users['firstName'] . '</td>';
    echo '  <td>' . $users['lastName'] . '</td>';
    echo '  <td>' . $users['emailAdd'] . '</td>';
    echo '  <td>' . $users['gender'] . '</td>';
    echo '  </tr> ';

}

echo '</table>';

        $conn = null;

    catch (PDOException $e) {
        $conn = null;
        exit("Connection failed: " . $e->getMessage());
    }
?>

Answer 1

您缺少尝试阻止

的结束括号

$conn = null;
}// this brace
catch (PDOException $e) {
    $conn = null;
    exit("Connection failed: " . $e->getMessage());
}

您的INSERT命令（缺少括号，额外的半冒号）中也存在语法错误，并且可以使用SQL注入。我不想向您介绍安全性，但您正在使用PDO，因此您至少可以准备好查询：

$sql = "INSERT INTO userProfile
        (username, firstName, lastName, emailAdd, gender, userPassword, birthday, profileDesc) 
        VALUES (:lastname, :firstname, :emailadd, :gender, :userpassword, :date, :profiledesc)";


$conn->prepare($sql);
$conn->execute(array(
                ':lastname' => $lastname ,
                ':firstname' => $firstname,
                ':emailadd' => $emailadd,
                ':gender' => $gender,
                ':userpassword' => $userpassword,
                ':date' => $date,
                ':profiledesc' => $profiledesc
));

Answer 2

格式化代码可帮助您解决问题。我想这是语法错误，但是，如果你还是找不到它为什么会这样。 catch阻止要求try关闭，就像

一样

try { smth } catch {

但是，您的try区块中没有右括号。

可能需要在$conn = null;我猜

之后

Answer 3

您需要先关闭try阻止，然后再致电catch：

$conn = null;

} catch (PDOException $e) {

我一直收到错误＆＃34;语法错误，意外发现＆＃39; catch＆＃39; （T_CATCH）＆＃34;
